layers: Add validation for destroyed layouts

Add three tests to flag with descriptor set update operations are being
done to descriptor sets with destroyed descriptor set layouts. The tests
use overload VUID (generic "must be valid * handles) which need to be
replaced with specific ones when they are added to the spec.

VALIDATION_ERROR_15c00280 (write dst must be valid) ->
	write dst created from destroyed layout
VALIDATION_ERROR_03207601 (copy dst must be valid) ->
	copy dst created from destroyed layout
VALIDATION_ERROR_0322d201 (copy src must be valid) ->
	copy src create from destroyed layout
